The foundation of irreligious criticism is: Man makes religion, religion does not make man. Religion is, indeed, the self-consciousness and self-esteem of man who has either not yet won through to himself, or has already lost himself again. But man is no abstract being squatting outside the world. Man is the world of man – state, society. This state and this society produce religion, which is an inverted consciousness of the world, because they are an inverted world...Religious suffering is, at one and the same time, the expression of real suffering and a protest against real suffering. Religion is the sigh of the oppressed creature, the heart of a heartless world, and the soul of soulless conditions. It is the opium of the people.The abolition of religion as the illusory happiness of the people is the demand for their real happiness. To call on them to give up their illusions about their condition is to call on them to give up a condition that requires illusions. The criticism of religion is, therefore, in embryo, the criticism of that vale of tears of which religion is the halo.Criticism has plucked the imaginary flowers on the chain not in order that man shall continue to bear that chain without fantasy or consolation, but so that he shall throw off the chain and pluck the living flower. The criticism of religion disillusions man, so that he will think, act, and fashion his reality like a man who has discarded his illusions and regained his senses, so that he will move around himself as his own true Sun. Religion is only the illusory Sun which revolves around man as long as he does not revolve around himself.
There may be some truth (atheists) do not need to believe in a god to be good, but then if they do not believe in a god, who do they believe gives the Universal Law of following good and shunning evil? Obviously, mankind. But then that is a dangerous thing, for if a man does not believe in a god capable of giving perfect laws, he is in the position of declaring all laws come from man, and as man is imperfect, he can declare that as fallible men make imperfect laws, he can pick and choose what he wishes to follow, that which, in his own mind seems good. He does not believe in divine retribution, therefore he can also declare his own morality contrary to what the divine may decree simply because he believes there is no divine decree. He may follow his every whim and passion, declaring it to be good when it may be very evil, for he like all men is imperfect, so how can he tell what is verily good? The atheist is in danger of mistaking vice for good and consequently follow another slave master and tyrant, his own physical and mental weakness. Evil would be wittingly or unwittingly perpetrated, therefore, to recognise the existence of a perfect divine being that gives perfect Universal Laws is much better than not to believe in a god, for if there is a perfect god, they will not allow their laws to be broken with impunity as in the case with many corrupt judges on earth, but will punish accordingly in due time. Therefore, to be pious and reverent is the surest path to true freedom as a perfect god will give perfect laws to prevent all manner of slavery, tyranny and moral wantonness, even if we do not understand why they are good laws at times.
